Description

BOILER TANK

The utility model relates to equipment for the transport of slurry, hardening and powdery cargo on railways, mainly to tank boilers.

Known boiler tank rail, containing two closed

end bottoms and a cylindrical shell of a sheet of identical thickness,

see Instructions for filling, draining and transporting liquefied petroleum gases in tank rail cars, E ,, redra, 1980, pp. 3-9, Approved by the Ministry of Gas Completion on 12.28.79 attached.

The main disadvantage of the known technical solution is the high metal structure.

A well-known railway tank, adopted as a prototype, comprising a housing with a safety-inlet valve om, a hatch, and a non-bulk device made of bottoms and a shell consisting of lower

it and the upper parts with different thickness walls, the wall thickness of the upper part, less than the wall thickness of the lower part, the lower part of the housing

the boiler can be equipped with a heating casing for half its circumference.

See Tanks. Device, operation, repair. Help manual. M. Transport, 1990, pp. 4-12.

The main disadvantage of the known technical solutions is also

is a high metal construction; low technological design.

The purpose of the technical solution is to reduce the metal consumption of the tank boiler and increase the manufacturability of the design,, ;; . % The goal is achieved by the fact that the shell of the boiler body,

made from the lower and upper parts of a sheet of various thicknesses,

the upper part of the shell is made (up to 270 °) of the circumference of the boiler body; the case is made of three shells of various lengths - two short extreme and one long middle; the upper part of the short shell is made of a single sheet; the upper part of the middle long shell is made of several longitudinal strips - more than one; bottoms are made of a sheet with a thickness equal to the thickness of the sheet of the lower part of the shell or more; extreme short shells are made of a single sheet of equal thickness

sheet thickness of the lower part of the middle shell; the lower part of the middle shell is made with a slope towards its middle, the lower part of the boiler body is equipped with a half-circle heating casing for transporting viscous or thickening products.

The implementation of the upper part of the shell (up to 270 °) of the circumference of the boiler body allows to reduce the metal consumption when the rigidity is sufficiently high, i.e. strength characteristics.

With increasing thickness of the sheets of the lower and upper partial shell

While maintaining the calculated difference in the thickness of the sheets, the girth angle of the upper part of the shell increases to 270 ° so that the support legs are placed on the lower part of the shell, giving the angle of girth of the sheets of the lower parts of the extreme 5) more than the angle: grip of the sheet of the lower part of the middle shell.

The essence of the technical solution is illustrated by the description and drawing, where in FIG. I shows a general view of the tank boiler with one shell of different thickness; in FIG. 2 is a general view of a tank boiler with three shells of different thicknesses; in Fig.3 - a General view of the boiler tank with three shells, medium thickness; in Fig.4 - section aa in Fig. 1,2, 3.

The boiler of the tank includes a cylindrical shell I, welded from longitudinal sheets (strips), and the upper part 2 of the shell I is made of several strips 6j MeHee thickness of 63 sheets

the lower part 3 of the shell I, two elliptical bottoms 4 - from a sheet of thickness B2 equal to the thickness 63 of the sheet of the lower part 3 of the shell I or more. The upper part 2 of the shell I is made up to 270 of the circumference of the shell I, Fig. The shell I is made of three shells of different lengths, two short extreme 5 and one long middle b, upper part 2

short shell 5 is made of a solid sheet of figure 2 with a thickness equal to the thickness of the sheet of the upper part 2 of the middle shell 6.

The average long shell 6 is made of several bands, more than one. Extreme short shells 5 are made of a single sheet with a thickness equal to the thickness of the sheet of the lower part 3 of the middle shell 6 of Fig.Z. The lower part 3 of the middle shell b is made with a slope to its middle. In the upper part 2 of the boiler of the tank along the vertical axis of symmetry there is a moonroof 7, next to which a drain-filling device 8 is installed, with safety-V; start valve. To prevent longitudinal displacements, the boiler is connected to the frame 9 with shaped legs 10 welded to its lower sheet 3. Vertical and lateral movements prevent the tightening clamps C. The discharge and filling device 8 can be performed as with a top load and

by unloading, and with top loading and lower unloading. The angle of grasping the sheets of the lower parts 3 of the extreme shells 5 is made greater than the grasping angle of the sheet part 3 of the middle shell 6. The lower part of the boiler body can be equipped with a heating casing for half a circle.

With tanks work as follows. Regardless of the download technology, they perform operations common to all types of operations:

They put the tank at the loading point, brake, check the technical condition, prepare for filling, connect the communications of the loading point to the elements of the tank loading device, load the cargo into its boiler with control of the filling level, pressure, temperature of the GRU, disconnect the communication of the loading point, prepare and send tanks. After arriving at the destination, the tanks are delivered to the unloading point, braked, the technical condition of the tank is checked, the tank is prepared for unloading, the communications of the unloading point are prepared for the elements of the tank unloading device, the cargo is unloaded, the tank is prepared for dispatch. CJL is repeated.

The use of a technical solution of a useful modezh in the design of a tank boiler allows it to reduce its metal consumption, increase manufacturability, and environmental safety. The technical solution was created during the performance of a job. Main% 1ZH KD S..a
